I need to get smaller feelers then. My .04mm won't fit into the foward intake do they even sell something smaller?  I should get inches instead
my micrometer is in inches too

.04mm is just over .001". I don't think you'll find much thinner than that.

Are your closers really loose?

I'm checking right now... The top cylinder if the rod is in to stop the cam from spinning, can you check it then? The intake is locked tight at that point. I'm checking it when the dot is at the 7oclock position... Again ds1000...

I really don't understand this... My valves are cold so the readings should be larger? I
here's my notes

horizontal
exhaust
unloaded .05 mm
loaded no change cannot get closer to spin

Intake
cAnnot fit feeler
cannot get closer to spin but I feel the closing rocker arm click when I push it down.

Vertical
exhaust
unloaded tad less than .04mm
loaded .07mm

intake
loaded .05mm
unloaded.04mm

however I'm still not sure if I'm doing the vertical cylinder right. I have the valves all closed at the 7 o'clock pos. I think the cam lock is for setting the belt only.

Not sure why my readings are so different from before.. another thing i noticed.. those helper springs are really make the beast with two backsing strong!

checked again today, same results. looked up some stuff on the DMF, 7 oclock on the vert pully or 3 oclick facing the horizonal pully will yeild TDC for vertical cylinder.


still cant figure out wtf is up with my readings. There are some topics that suggest i use the smallest shim and use that as a basis of how large the new shim i purchase be....

Yeah...you need to be able to measure. If you have to change shims to do it...so be it.

What isn't making sense is that both the openers and closers are tight.

There are marks on the bike for where the belt pulleys line up.

Pull your belts to measure. It's waaay easier.

i agree with the belts, it makes life easier, but at the same time those helper springs are REALLY tough. i wish i had a special tool to spin the cams!

im trying to figure out why i have the same issues. this is assuming that the guy who did my vlaves durring my valve guide warranty didnt mess up because they were pretty off when Jay checked them out (ECS).

how much weight do you have to apply on the closing rocker to get the valve to settle?

You let Jay adjust your valves.... :o :o :o :o just kidding

Why are you trying to spin the cams?

Still...

why do you need to spin the pulleys past the range where the valves are closed?

mostly to get the vertical belt back on. theres not enoug harea for a finger to fit in there. and its not like i can use the belt to spin it either cause then the belt wouldnt go back on the drive pulley.

i also turn it to cycle the cams and recheck my measurements. on the horizontal its fine but the verticsal one is  a big pita

yeah...

getting the vertical into position is tricky, but it's not that hard...

even an old buck like me can do it.

Young guy like you should have no issue. ;D

You don't have to spin the pulleys/cams to check measurements.

The important thing is to make sure the half rings are seated on the closers.

Can you feel much drag on the cams when you spin the pulley inside the range where the valves are closed?

i dont remember posting that.....


let me give it another try though....

theres no drag when the pully is around the area of TDC, its spin freely for about 90 degrees and then it actuates the rocker arms for intake. normal operation from what it seems.  and ducati should add a dot on the pulley for vertical TDC so you can find it without belts.
